Stability and Control characteristics of the Early Mark Spitfires

Exactly.

Your thrust vector adds to gravity, lift opposes drag <unless you dive a zero lift angle>

In short, away you go...

Negative....if you are throttle closed then there is no thrust vector to add and a disking prop adds to drag, acceleration is 'not' infinite (see Captaindoggles post for a reason), in some aircraft a vertical dive will not even reach Vne.

since when did lift oppose drag?, lift opposes weight and thrust opposes drag, lift actually adds to drag because lift generates induced drag, if you fly at 'zero lift' then there is no induced drag.

Like the one in my hanger???

Ohh!....a thorp t18....that's gotta be one of the ugliest mothers I've ever seen.

That passenger is Col. Phil Lacey.

Col. Lacey flew P-40's, P-39's, and P51's with the 8th USAAF in World War II. In Korea he flew F-86's and Vietnam, Canberra bombers.

You don't what aerobatics is until you seen Phil take the stick, LOL. That old man can fly the paint off an airplane.

And yes, he reads and abides by the Operating Notes.....

Is this supposed to convince us you know what you are talking about? because I'm even less convinced of that now.
